Bleomycin-induced upper lobe fibrosis: a case report.

We report a case of late-onset pulmonary fibrosis involving the upper lobes that occurred in a young man treated with bleomycin for mediastinal germ-cell carcinoma. The parenchymal lesions became clinically apparent about two years after chemotherapy had been completed, with a slowly progressive course and sparing the lower lung fields during follow-up. Other possible diagnoses could be excluded on the basis of the patient's clinical history, laboratory tests and pathological findings.
